The layout of this reaction may differ from that in the pathway view due to the constraints in pathway layout

SUMO1 is transferred from cysteine-173 of UBA2 to cysteine-93 of UBC9 (UBE2I) in a transthiolation reaction (Desterro et al. 1999, Okuma et al. 1999, Tatham et al. 2003, Lois and Lima 2005, Wang et al. 2007, Werner et al. 2009). The UbL domain of E1 recruits E2 into proximity for the transfer of SUMO (Lois and Lima 2005, Wang et al. 2009),
